Christiansen built the first grating array for scanning the sun at the radio astronomy field station at Potts Hill, New South Wales. A later array at Badgerys Creek, New South Wales, the Chris Cross Telescope, was named after Christiansen.

In 1981 he was made an honorary fellow of the Institution of Engineers Australia.[12]

Royal Commission on Espionage

On 27 January 1955, Christiansen appeared before the Royal Commission on Espionage.

He was extensively questioned in relation to his own political orientation, the influence of certain of his wife's siblings Template:Em-dash one of whom had the code name "Tourist" Template:Em-dash and, in particular, in relation to the fact that he was not only mentioned in secret Russian Ministry of Internal Affairs (M.V.D.) documents turned over to the Australian authorities by Vladimir Petrov, but also had been of such interest to the Russians that they had given him the unique code name of "Master".

It was determined that there was no grounds for any suspicion of him ever having any connexion with the M.V.D.; and, in the process of his examination, the counsel assisting the Commission, George Pape, produced statements from both Mr. and Mrs. Petrov asserting that Christiansen was not known to them at all.[13][14][15]
